Application filed January 27, 1908. Serial no. 412,768.

Be it known that I, IVER R. ANDERSON, a citizen of theUnited States,residing at Des Moines, in the county of Polk and State of Iowa, haveinvented a new and useful Peanut-Roaster, of which the following is aspecification.

The objects of my inventionare' to provide a peanut roaster in which aninternal combustion engine is provided, which engine may be used forpropelling the peanut roaster, or for rotating the roasting cylinder,and in which the heated products of combustion fromthe engine areutilized for the purpose of heating or cooking peanuts or otherarticles.

A further object is to provide means whereby said products of combustionare so distributed as to utilize their heat to its maximum efliciencywithout having the gases thereof come in direct contact with the peanutsor other articles being cooked.

' A further object is to provide a warming pan for peanuts or similararticles, which pan is so arranged and connected with the water jacketof the engine, as to be heated by the water surrounding the engine.

A further object is to provide a simple, durable and inexpensiveroasting cylinder especially designed for use in connection with adevice of this class, in which the heat is supplied by. the exhaust froman internal combustion engine.

My invention consists in the construction, arrangement and combinationof the various partsof the device, whereby the objects contemplated areattained, as hereinafter more fully set forth, pointed out in my claims,and illustrated in the accompanying drawings, in which Figure 1 shows aside elevation of the complete device embodying my invention, with partsbroken away to show certain details of construction. Fig. 2-shows' avertical sectional view onthe line 2-2 of Fig. 1. Fig. 3 shows avertical sectional View on the line 33 of Fig. 1. Fig. 4 shows an endview of the roasting cylinder, and Fig. 5 shows a side View of same. 3 A

Referring to the accompanying drawings,

I have used the reference numeral 10 to indicate the frame-of thedevice. This frame is supported upon a rear axle 11 having the drivingwheels 12 fixed thereto, and aforward or steering axle 1'2" having thewheels 13 thereon.

Mounted on the rear axle 11 are two sprocket wheels 14 for driving same,and connected with the forward axle is a steering device 15 for guidingsame. These parts are all of the ordinary construction, and ofthemselves form no part of my present invention, and hence are notherein specifically illustrated and described.

Mounted within the body portion of the frame is an internal combustionengine 16 of ordinary construction, the cylinder of which is surroundedby a water jacket 17, also of the ordinary kind. A shaft 18 is rotatablymounted in'the frame, and is provided with a clutch member 19 fixedthereto. A sprocket wheel 20 is loosely mounted thereon, and having atone end a clutch member 21 to mate with the clutchmember 19, and on itsother end a clutch member 22. A smaller sprocket wheel 23 is rot-atablmounted bn the shaft 18'and is provide with a clutch member 24 to matewith the I clutch member 22. A lever 25 is provided for sliding thesprocket wheel 20 so that the clutch members thereon may move intoengagement with other mating clutch members. When the sprocket wheel 20is moved into engagement with the clutch member 19, then the shaft 18'will be rotated, and when it is moved into engagement with the clutchmember 24, the sprocket wheel 23 will be rotated and the shaft 18 willbe stationary.

On the ends of the shaft 18 are the sprocket wheels 26,-each of which isconnected by a chain 27 with the sprocket wheels 14 on the driving axle.

Mounted in the top of the body of the frame is a'warming pan forme of anupper layer 28 and-a lower layer 29spaced apart to form a water chamberbetween them. This water chamber is connected with the water jacket ofthe en "ne by means of a pipe 30 communicating etween the bottom of thetank and the botto tn of the water jacket, and a pipe 31 communicatingbetween the upper portion of the water chamber of the warming pan, andthe top portion of the water jacket, as clearly shown in Fig. 3. By thismeans, the heated water in the jacket will rise through the pipe 3 1 andheat the warming pan, and as the water piortion I cools in the warmingpan, it will descend through the pipe 30 to the bottom of the waterjacket.

At the forward end of the frame is a cylindrical roasting casingcomprisinga lower stationary part 32 and a hlnged cover 33 thereon. Thiscasing is provided at its top with a discharge pipe. 34. Detachablymounted in the casing is a shaft 35 on which wheel 23, as clearly shownin Fig. 2. 'The v of the rows of tubes46, as shown in Fig. 5.v

roasting cylinder comprises two hubs 41 fixed to the shaft 35. Each hubis provided with a spider 42 designed to support the roasting cylinder.'The roasting cylinder proper is formed of an outer cylinder 43 and aninner cylinder 44'spaced apart from each other. The cylinder heads 45are provided to cover the space between the cylinders, said cylinderheads however, are open at the ends of the inner cylinder 44. I-havealso provided a series of rows of open-ended tubes 46 leading from theinterior of the inner cylinder 44 to the exterior of the outer cylinder.The chamber between the inner and outer cylinders is designed for thereception of peanuts or other articles to be roasted or cooked, and Ihave provided for attaining-access to this chamber as follows: The outercylinder 43 ,is provided with a longitudinal opening in one side, whichopening is normally covered by means of a segmental slide 47. This slideoperates in tracks 48 formed for it on the stationary The opening in Thereference numeral 49 indicates the exhaust pipe of the engine. Thisexhaust pipe is provided with a branch -50, and

. both the pipe and its branch are extended to points adjacent to theopposite ends of the inner cylinder 44, as clearlyshown in Fig. 2, sothat the discharge from the engine will pass through the endsof theinner cylinder 44 and into said cylinder, and then out through the tubes46 to the space between the-outer cylinder and the casing 32 and 33, andit will then finally escape through the discharge pipe 34.

In practical use, and assuming that it is desired to transport themachine, then the operator starts the engine, and throws the lever 25 toposition with the clutch 21 .in engagement with the clutch 19. In thisway, the engine will propel the machine, and the operator may steer itby the steering device 15. When-it is desired to roast peanuts,

the operator manipulates the lever 25 to will come in contact with thepeanuts or other articles being cooked. When it is desired to haveaccess to the interior of the roasting cylinder, the operator elevatesthe cover 13 and bodily removes the shaft 35 with the roastin cylinderthereon, then the slide 47 is with rawn, and the entire contents of theroasting cylinder may be easilydischarged, and the cylinder be refilled.
